HEEL GAUGE.

Application filed June 20, 1921. SerialNo. 478,952.

To all whom it may concern Be it known that I, lVILLmM FoLLn'r, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Heel Gauges, 'of which the following is a specification.

My invention relates tomeasuring instruments and more particularly to heel v gauges for shoe lasts. i

It is customary for the shoe manufao turer to supply the last maker with a tem plet or form or in some instances with a sample last disclosing the particular cnr vature oftlie heel of the last or shoe which has been adopted as a standard by such This curve varies somewhat among different shoe manufacturers. Some manufacturers prefer a heel curve of'considerable depth, while others adoptone of less degree. but are irregular curves, and in different in stances, the point of greatest depth varies among diil'erent manufacturers. Moreover,

this standardized curve is usually supplied for only one size of lasts. The size L last is usually adopted as the standard and lasts of other sizes are made to agree therewith except for certain modifications due to the increased or decreased sizes. Itis customary to maintain the standardized curve so that which this curve is tilted inward or out wardly about an imaginary point at the apex of the base angle of the last heel formed by the juncture of the heel curve ter this curved outline is tilted inwardly or from the standarized, size 4 last, approxi- These curves are not circular last, or in the same relation with the last body for each last of a given size. If the pitchof the curve is slightlygreater in one lastthan in the other last-of a; given pair,

one of the shoesmade over's'ueh a last will be tight'inthe heel andwill bind the foot of the wearer. a H

. The object of the present inventionis to afford a simple economical and accurate gauge by which not only the curvature or and annoy contour of the heel outline may be determined,.but also the predeterminedpitchor angular relation of the heel curve with the sole or bottom of the lasts of different sizes determined; This is important in order that all lasts of a given size may be enact duplicates of each other in this respect and in order that lasts of different sizes may agree accurately with the shoe uppers for such sizes as graded upon the leather grad- .ing machine.

\ A further object "of the, invention is to provide in such a gauge ad ustment means whereby the gauge may be readily varied to accommodate lasts of different sizes, and

for accurately determining the pitch of the heel curve for any given sizeof last. I

With the above primary and other incisv dental objects in view as will more fully-appear in the specification, the invention consists of the features of construction, the parts and combinations thereof and the mode of operation or their. equivalents as hereinafter described and set forth in the claims.

Referring to. the drawing, shown the preferred, but not theionly embodiment-of theinvention, Fig. 1 is a perspective view of the adjustable heel gauge applied tothe heel of a last, illustratingthe mode of application, and the gaugingipoint.

The herein described method of grading shoe lasts by tilting the heel curve forwardly 0r rearwardly to di-iierent predetermined degrees in accordance with different sizes at lasts, is described in and made the subject matter of a divisional application for Letters Patent, Serial l lo. 83,1345, filed May 27, 1925.

From the above description it will be ap parent that there thus provided a device of the chz'iracter described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

Vhile in order to comply with the statute the invention has been described in language more or less specific as to structural features,

it is to be understood that the invent-ion is not limited to the specific details shown, but that the means and construction herein disclosed comprise butone of several modes of putting the invention into e'dect, and the in vention is therefore claimed in any ot'its forms or modifications within the legitimate and valid scope of the appended claims.

Having thus described my invention, I claim:

5. In a heel gauge for lasts, an arcuate template agreeing with the predetermined rear outline ofthe last heel, and a support therefor engageablelwith a predetermined" throughout a range of different sizes of lasts,

the pitch of such curve in. relation with other parts of the last varying with variations of size of the lasts, characterized an arcuate template agreeing with the predetermined rear contour of the last heel, last engaging means, said arcuate template being capable oi oscillatory movement aboutthe lower end of the last heel contour as defined by said template, and. means tormaintaining the template 1n ad usted relation w th said last engaging means.

7. In a heel gauge for support having gauge points thereon, a blade pivotally mounted thereon, a template detachably carriedby the blade, an adjusting shoe lasts, a main screw interconnecting; the pivoted blade and support and means for locking the blade to maintain the template in different posit-ions ot' oscillatory adjustment in relation with the gauge points of the support.

8.111 a heel gauge for shoe lasts, two interpivoted members, one havin gauge points thereon for engagement with the last,

the other being curved to agree with the rear contour of the last heel, an adjusting screw for varying the relative adjustment of said member, one of said members having sealing means by which the variation of adjustment may be determined in predetermined units of measurement. I

9. Ina heel gauge for shoe lasts, two inter pivoted members, one of the members hav inn gauge points thereon'lor engagement with the last, a detachable template car ried by the other member the contour of which agrees with that or" the predetermined outline of the last heel, means for relatively ad L sting SillCl, members to measured degrees of pitch of the template in relation with the gauge points of the first mentioned member to correspond with the heel pitch of lasts of different sizes.

10. Means for gauging the heels of shoe lasts wherein the pitch of the heel curve in relation with other portionsof the last varies with variations of last sizes, comprising two relativelyadjustable members, one of which has gauge points thereon for engagement with the last, the other of which is curved 7 ing seicl Curved member to Various positions angulerly disposed in relation to said first named member and corresponding to predm terminecl relative degrees of pitch of the heel curve in relation with the portions 01.
